Obviously, i would call a licensed electrician, but is the changeover something i should tell/ask my landlord? a) will running a 220V device cause the neighboring tenants tv's go fuzzy, cause flickering lights etc.?
No it shouldn't unless you're on the same circuit. If you have your own meter it should only be your lights that flicker if they flicker at all. FWIW, I wired my own 150 service to my home shop from the house. All residential in my area are a minimum of 200 amps. My TVs don't flicker from the welders, 110 or 220. Now the compressor is another story. It's 10HP single phase and draws 42amps on start and 24 running. As it gets closer to full my lights will flicker just a bit. Since it only runs for 1min 15sec per cycle I don't mind much.
dont get a 110 century either! Ive got an older one that a friend traded me for some drywall work. it has the wire hot all the time and wont put out enough amps to consistantly weld heavy steel.
